Diagnosis

This species may be separated from other Caribbean and Central American Charinus   by means of its dark coloration and secondary sexual dimorphism. Among the Caribbean species in which the male is known, C. aguayoi   is the only species which exhibits the most distinct secondary sexual dimorphism, i.e., males possess much longer pedipalp segments than females. Compared to other species in which the tibia of leg I consists of 21–23 articles and the leg I tarsus consists of 33 articles, C. aguayoi   differs from C. dominicanus   , C. muchmorei   and C. wanlessi   in the presence of median eyes ( Fig. 13A View Fig ). An ontogenetic difference is evident in the size of the median eyes, which are much smaller in adults than immatures.

Etymology

Patronym honoring Dr Carlos Guillermo Aguayo, a Cuban scientist specializing in tropical invertebrates ( Moyá-Guzmán 2009).

Supplementary description

CARAPACE. Six anterior setae ( Fig. 13A View Fig ); frontal process triangular. Small granules densely scattered between ocular triads and among sulci. Median eyes present but median ocular tubercle shallow ( Fig. 13A View Fig ); pair of setae on median ocular tubercle; lateral eyes well developed, seta posterior to each lateral ocular triad ( Fig. 13A View Fig ); lateral ocular triad well separated from carapace margin ( Fig. 13A View Fig ).

STERNUM. Tritosternum projected anteriorly with typical setation, long, surpassing base of pedipalp coxae ( Fig. 13B View Fig ); other sternal platelets narrow and concave, each divided (forming pairs), with seta on its top; pentasternum with two setae posteriorly and without setae near membranous region.

OPISTHOSOMA. Ventral sacs and ventral sac cover absent.

GENITALIA. Female genital operculum with large setae posteromedially and some smaller setae near margin ( Fig. 14A–C View Fig ); posterior margin convex ( Fig. 14A–B, E View Fig ); gonopod cushion-like with basal sclerotization ( Fig. 14A, C View Fig ); slit sensilla on lateral side of genital operculum on ventral surface ( Fig. 14F View Fig ). Male gonopod with apex of fistula and base of lateral lobe strongly sclerotized; lateral lobe 2 fimbriate, short ( Fig. 15A–B, E View Fig ); lamella medialis short ( Fig. 15A View Fig ); dorsal lobe with long, acute projections apically ( Fig. 15A–C, G View Fig ); processus internus short ( Fig. 15F View Fig ).

CHELICERAE. Small tooth slightly projecting from retrolateral surface of basal segment, opposite to bifid tooth; retrolateral surface of claw with small row of setae at base of claw; claw with four or five teeth; row of around ten setae on prolateral surface of basal segment; bifid tooth with dorsal cusp larger than ventral cusp.

PEDIPALPS. Coxal dorsal carina with three setae on anterior margin, without setae encircled by round carina. Femur with three dorsal spines and three ventral spines ( Fig. 13D View Fig ); two prominent setiferous tubercles between dorsal spine 1 and proximal margin; setiferous tubercle between ventral spine 1 and proximal margin. Patella with three dorsal spines in primary series ( Fig. 13E View Fig ); prominent setiferous tubercle distal to spine I, one-third length of spine I; two ventral spines; distinct setiferous tubercle between spine I and distal margin. Tibia with ventral spine distally and seta between spine and distal margin. Tarsus with two dorsal spines, distal spine long, more than half length of tarsus, proximal spine one-third length of distal spine ( Fig. 13C View Fig ); cleaning organ with 29–33 setae in ventral row.

LEGS. Tibia of leg I with 21 articles, tarsus I with 32–34 articles; first tarsal article three times as long as second; tarsal organ situated near base of claw ( Fig. 16A, C–D View Fig ); rod sensilla with four setae in shallow groove ( Fig. 16B, E View Fig ). Leg IV basitibia with three pseudo-articles, without sclerotized, denticulate margin projecting from apex of articles; trichobothrium bt situated in proximal third of pseudo-article; distitibia trichobothrium bc situated closer to bf than to sbf; sc and sf series each with five trichobothria.
